IsEasy USF-S4.4CF-SSL

The IsEasy USF-S4.4CF-SSL never switches off, and its certified 228 kWh a year works out to about $43 on a U.S.-average electric bill — roughly $3.58 a month for an average continuous draw of 26 watts. Efficiency-wise it's unremarkable in a good way: within 7% of the median certified compact refrigerator (rank 653 of 1589). The same unit costs $28 a year in North Dakota but $106 in Hawaii — electricity rates, not the appliance, make the difference.
